【解析】1.句意:當(dāng)一項(xiàng)發(fā)明創(chuàng)造問世時(shí),對發(fā)明者而言有三種可供選擇的。因此D項(xiàng)courses(做法)符合句意。
2.句意:他可以把這項(xiàng)發(fā)明公布于世,或,或申請專利。根據(jù)空格處前后句意推測,此處選C。意為“保密”。
3.句意:專利是發(fā)明者與國家之間達(dá)成的一種契約。因此A項(xiàng)granted(授予)正確。
4.句意:授予的專利發(fā)明者與國家之間達(dá)成的一種契約。此為動詞strike的過去分詞形式做后置定語。
5.句意:按照契約,發(fā)明者可以對自己的成果在一定期限內(nèi)享有壟斷權(quán),壟斷后,他就得把發(fā)明的細(xì)節(jié)問題公之于眾。Terminate意為“結(jié)束”,此為時(shí)間狀語從句,從句中缺謂語動詞。故選D。
6.句意:只有在極其特殊的情況下才可以延長專利期限。此句為only短語位于句首,句子應(yīng)部分倒裝,主語為thelifespanofpatent,因此用系動詞is。
7.此處主語為專利,所以應(yīng)該用被動語態(tài),is被提前了,因此選C。
8.句意:曾經(jīng)最長的專利延期名額給了GeorgesValensi。這里應(yīng)用grant的過去分詞形式表被動。
9.句意:1939年他就取得彩色電視接收器線路的專利,而且這一專利延續(xù)到1971年,因?yàn)檫@項(xiàng)專利在其大部分正常期限內(nèi)都沒有彩電可供,這樣這項(xiàng)專利無望獲得回報(bào)。因此,send(發(fā)送)符合句意。而且,空格前為動詞不定式to,因此選D。
10.句意:因?yàn)橐豁?xiàng)專利到期后,就永遠(yuǎn)了。A項(xiàng)符合句意和邏輯。
11.句意:因此,局所屬的圖書館架子上有成千上萬種專利。根據(jù)句意選C。
12.句意:如果半個(gè)世紀(jì),任何人都可以自由使用。longer長久的,長期的;older多年的,長時(shí)間的;weaker虛弱的;younger年輕的。因此選B。
13.句意:實(shí)際上,專利專家們常對開發(fā)有效專利而又避免高額費(fèi)用的人提出建議,避免侵犯他人專利的有效辦法就是使用過期專利。此處,wish符合句意,此處邏輯主語為anyone,因此選D。
14.句意:實(shí)際上,專利專家們常對希望開發(fā)有效專利而又避免高額費(fèi)用的人提出建議,避免侵犯他人專利的有效辦法就是使用過期專利。Live實(shí)況播送的;dead無效的;working起作用;recording記錄的。因此選A。
15.因?yàn)橛萌魏纹渌绞焦加^點(diǎn)都會使之失效。C項(xiàng)permanently(永久地)符合句意。
16.句意:因此,傳統(tǒng)上,從其他印刷材料上想出辦法是。C項(xiàng)safe(安全的)符合句意。
17.句意:眾多現(xiàn)代技術(shù)的進(jìn)步都是這些法律安全的考慮。因此D項(xiàng)based(根據(jù))符合句意。
18.句意:任何一個(gè)經(jīng)常專利和發(fā)明的人很快會得知。B項(xiàng)involved(參與了)符合句意。
19.句意:只有把握時(shí)代的需求,跟上新技術(shù)的步伐,專利才能變成商業(yè)實(shí)踐,做到名利雙收。此處為強(qiáng)調(diào)句型,應(yīng)用引導(dǎo)詞that。
20.句意:電視生成原理許多原創(chuàng)思路都起源于19世紀(jì)后期和20世紀(jì)初。
2.單選題

3.單選題
Itisthefirsttimethathe(
)theschoolregulation.
問題1選項(xiàng)
A.isgoingtoviolate
B.hasviolated
C.violates
D.violated
【答案】B
【解析】【試題解析】考查語法結(jié)構(gòu)。本題考查的是同位語從句中的動詞時(shí)態(tài)問題。Itisthefirsttimethat...這個(gè)句子結(jié)構(gòu)中,使用動詞的現(xiàn)在完成時(shí),表示對于過去經(jīng)歷的總結(jié),句意為:這是他第一次違反學(xué)校規(guī)則。故選項(xiàng)B符合題意。
4.單選題
Rockmusicusually______theyoungpeopleinmostcountries.
問題1選項(xiàng)
A.appliesto
B.appealsto
C.amazes
D.actress
【答案】B
【解析】【試題解析】考查詞義辨析。A選項(xiàng)appliesto“適用于;向……提出申請”;B選項(xiàng)appealsto“呼吁;要求;對……有吸引力”;C選項(xiàng)amazes“使吃驚”;D選項(xiàng)actress“女演員”。句意:搖滾樂通常______大多數(shù)國家的年輕人。根據(jù)語境,這里B選項(xiàng)appealsto“對……有吸引力”搭配youngpeople比較合理,意思指年輕人喜歡搖滾樂。因此B選項(xiàng)正確。

【答案】第1題:A
第2題:C
第3題:D
第4題:A
第5題:B
【解析】第1題:1.結(jié)合文章內(nèi)容可知,本文主要講的是在公眾面前講話的重要性,選項(xiàng)B,C,D是文中提到的細(xì)節(jié),不是本文主旨,所以選項(xiàng)A正確。
2.根據(jù)第二段第一句“Eveninjobsrelyingon...collegestudentsrealize.”即使是在依靠專業(yè)技能的工作中,對公眾演講技能的機(jī)會和需求也比許多大學(xué)生意識到的更為普遍。由此可以推斷,公眾演講對技能要求高,很難保持。選項(xiàng)C符合原文。
3.根據(jù)第一段最后一句“Tospeakonsuchmatterseffectivelyenoughtoinfluencetheopinionsandactionsofothersistoexercisepower.”在這樣的問題上有效地發(fā)言,足以影響他人的意見和行動,就是在行使權(quán)力。也就是說,如果你想影響別人,你的講話一定要有效。選項(xiàng)D正確。
4.根據(jù)第二段的第二句“Theengineerfindsthatifhiscareeristoadvancehemustbewillingtoacceptmanagementdutiesthatincludespeakingtogroupsofemployees...”工程師發(fā)現(xiàn),如果他的職業(yè)生涯想要發(fā)展,他必須愿意承擔(dān)管理職責(zé),包括向員工群體發(fā)表演講...由此可以推斷,一個(gè)好的演講者在他的職業(yè)生涯中可能有更大的機(jī)遇。選項(xiàng)A符合原文。
5.根據(jù)第三段最后兩句可知,你可能不僅僅只是滿足于完成(演講)任務(wù),能夠增加聽眾的理解或說服他們是我們作為個(gè)體影響環(huán)境的最文明的方式之一。所有選項(xiàng)B符合原文。

【答案】第1題:C
第2題:D
第3題:A
第4題:B
第5題:B
【解析】1.事實(shí)細(xì)節(jié)題。根據(jù)第一段第二句“Thegovernmentlatertriedtocancel,itsdecision,butcongressmadethetravelbanapartofimmigrationlaw.”政府后來試圖取消這一規(guī)定,但國會將旅行禁令作為移民法的一部分。由此可知,選項(xiàng)C正確。
2.事實(shí)細(xì)節(jié)題。根據(jù)第六段第一句“TheUnitedStatesArmysponsoredthevaccinetrial.”美國軍方贊助了疫苗試驗(yàn)。由此可知,選項(xiàng)D正確。
3.事實(shí)細(xì)節(jié)題。根據(jù)第七段的一二句“Thairesearcherstestedthecombinationinmorethan16,000volunteers.Halfofthevolunteersgotthevaccine.Theothersgotaplacebo...”泰國研究人員對1.6萬多名志愿者進(jìn)行了測試。一半的志愿者接種了疫苗。另一半則使用安慰劑。由此可知選項(xiàng)A正確。
4.是非判斷題。根據(jù)第三段最后一句“yetweareonlyadozencountriesthatstillbarpeopleH.I.V.fromenteringourcountry.”我國(美國)也是僅有的十幾個(gè)禁止艾滋病人入境的國家之一。由此可知,選項(xiàng)A錯(cuò)誤,選項(xiàng)B正確;根據(jù)第五段第二句“ThefullresultsofthevaccinestudywerepresentedinlaterOctoberataninternationalconferenceinParis.”可知,在巴黎舉行的會議是公布研究結(jié)果而不是預(yù)防艾滋,所以選項(xiàng)C錯(cuò)誤;根據(jù)第五段最后一句“TheresearchersconfirmedthatthestudyinThailandproducedonly'modest'results.”研究人員證實(shí),在泰國進(jìn)行的這項(xiàng)研究只產(chǎn)生了“溫和”的結(jié)果,所以選項(xiàng)D也錯(cuò)誤。
5.事實(shí)細(xì)節(jié)題。根據(jù)倒數(shù)第二段第一句“Butcriticssaidthefindingscouldpossiblyhaveresultedfromchance.”批評人士表示,這些發(fā)現(xiàn)可能是偶然的。選項(xiàng)B符合原文。

第2題:C
第3題:D
第4題:B
第5題:C
【解析】1.【選項(xiàng)釋義】
1.What’sthethematicquestionofthepassage?1.這篇文章的主題問題是什么?
A.Howtodealwiththerelationsbetweenozonelayerandradiationdamage?A.如何處理臭氧層與輻射損害的關(guān)系?
B.Whatistheaveragethicknessofthestratosphericozonelayer?B.平流層臭氧層的平均厚度是多少?
C.Whydoesincreaseexposuretoultravioletradiationdestroymanylivingorganisms?C.為什么紫外線輻射的增加會破壞許多生物體?
D.Howisstratosphericozonecreatedandchanged?D.平流層臭氧是如何產(chǎn)生和改變的?
【考查點(diǎn)】主旨大意題。
【解題思路】通讀全文可知,文章第一段介紹了平流層臭氧是如何產(chǎn)生的,第二、三段講述了影響臭氧含量的一些因素,包括太陽活動、季節(jié)、天氣和緯度,以及解釋臭氧是如何被破壞和創(chuàng)造,但又能保持平衡,綜合理解可推斷,這篇文章主要是回答平流層臭氧是如何產(chǎn)生和改變的這個(gè)問題,故該題選擇D項(xiàng)“平流層臭氧是如何產(chǎn)生和改變的?”符合題意。
【干擾項(xiàng)排除】A項(xiàng)“如何處理臭氧層與輻射損害的關(guān)系?”、B項(xiàng)“平流層臭氧層的平均厚度是多少?”和C項(xiàng)“為什么紫外線輻射的增加會破壞許多生物體?”,原文沒有談到這三個(gè)問題,這三項(xiàng)屬于無中生有。
2.【選項(xiàng)釋義】
2.Accordingtothepassage,whatmostresemblestheprocessesthatdeterminetheamountofozoneintheupperstratosphere?2.根據(jù)文章,什么最類似于決定平流層上層的臭氧量的過程?
A.Automobileemissionsandseasonalfogsthatcreatealayerofsmogoveracity.A.汽車尾氣和季節(jié)性霧霾會在城市上空形成一層霧霾。
B.Plantingandharvestingactivitiesthatproduceacropwhosesizeisalwaysaboutthesame.B.種植和收獲活動產(chǎn)生的作物的規(guī)??偸窍嗤?/p>
C.Depositsandwithdrawalsmadeinabankaccountwhoseaveragebalanceremainsmuchthesame.C.在銀行賬戶上的存款和取款,其平均余額基本不變。
D.Assetsandliabilitiesthatdeterminethenetworthofacorporation.D.決定公司凈資產(chǎn)的資產(chǎn)和負(fù)債。
【考查點(diǎn)】推理判斷題。
【解題思路】首先定位第二段,該段對平流層上層的臭氧量變化過程有描述,根據(jù)前三句“由于氧分子的分裂直接取決于太陽輻射的強(qiáng)度,臭氧產(chǎn)生的最大速率發(fā)生在熱帶地區(qū)。然而,那里的臭氧被破壞的速度也最快,風(fēng)環(huán)流模式將富含臭氧的上層大氣帶離赤道。結(jié)果發(fā)現(xiàn),臭氧總量最大的地區(qū)是高緯度地區(qū)?!币约白詈笠痪洹叭欢诘厍虮砻娴娜魏我粋€(gè)地方,自然過程所維持的長期平均值被認(rèn)為是相當(dāng)恒定的?!睆闹锌芍瑹釒У貐^(qū)的臭氧產(chǎn)生速率是最高的,但是臭氧含量最高的是高緯度地區(qū),因?yàn)轱L(fēng)環(huán)流模式會將富含臭氧的上層大氣帶到高緯度地區(qū),這是自然過程維持的一個(gè)恒定的平均值,也就是說產(chǎn)生和帶走的臭氧量的平均值會保持恒定,這與C項(xiàng)“在銀行賬戶上的存款和取款,其平均余額基本不變”類似,故該題選擇C項(xiàng)。
【干擾項(xiàng)排除】A項(xiàng)“汽車尾氣和季節(jié)性霧霾會在城市上空形成一層霧霾”、B項(xiàng)“種植和收獲活動產(chǎn)生的作物的規(guī)模總是相同”和D項(xiàng)“決定公司凈資產(chǎn)的資產(chǎn)和負(fù)債”沒有表現(xiàn)出保持恒定這一過程,這三項(xiàng)屬于曲解原文。
3.【選項(xiàng)釋義】
3.WhichofthefollowinghastheLEASTeffectontheamountofozoneintheupperatmosphere?3.下列哪項(xiàng)對上層大氣中的臭氧量影響最?。?/p>
